# Developer Dashboard Final Fix Documentation

## Problem Resolved

### Issue
The developer dashboard was encountering an "Undefined variable $slot" error:
```
ErrorException
resources/views/layouts/developer.blade.php:113
Undefined variable $slot
```

### Root Cause
The developer layout was using `{{ $slot }}` (which is used in component-based layouts) but the dashboard view was using `@section('content')` (which requires `@yield('content')` in the layout).

### Solution
Changed the layout from `{{ $slot }}` to `@yield('content')` to match the dashboard view's `@section('content')` directive.

## Technical Fix Details

### Before (Broken)
```blade
<!-- Page Content -->
<main class="flex-1 overflow-x-hidden overflow-y-auto bg-gray-100">
    {{ $slot }}
</main>
```

### After (Fixed)
```blade
<!-- Page Content -->
<main class="flex-1 overflow-x-hidden overflow-y-auto bg-gray-100">
    @yield('content')
</main>
```

### File Changed
- **File:** `/resources/views/layouts/developer.blade.php`
- **Line:** 113
- **Change:** `{{ $slot }}` → `@yield('content')`
